Assigning Addresses to Pointers
When working with pointers, proper initialization is essential to ensure they point to valid memory locations and prevent unexpected behavior.
Address-of and Dereference operators
To assign a value to the pointer we have to use address-of operator and to access the value of the memory address we have to use dereference operator.
&
: the address-of operator, returns the memory address of its operand;*
: the derefence operator, returns the value that stored in the memory address.
main.cpp
Using the address-of operator, we can assign these addresses to pointers, creating a direct link between the pointer and the memory location it points to.
Tarea
- Declare a pointer with an appropriate data type.
- Initialize it with a
variable
memory address. - Output both the memory address the pointer points to and the value it holds.
